BACKING-UP DISTRIBUTCER.

Application filed December 19, 1914, Serial No. 878,1(12,

To allwhom it may concern:

Be it known that I, Eawaaa a citizen of the United States, and aresident of Jersey City, in the county of Hudson and State of NewJersey, have invented certain new and useful Improvements in Backing- UpDistributors, of which the following is a specification.

My invention relates to electrotyping, and the main object thereof is toprovide means for uniformly distributing the molten metal forming theback of an electrotype; a further object is to provide means forstraining the molten metal as it is poured over the copper shell to forma support therefor; a further object is to provide such a device whichis entirely independent of the electrotype and of the tray wherein it isplaced for backing-up, thereby enabling an operator to place the same atany position in the tray; and further objects are to provide suchdevices which are simple in construction and use, well adapted for thepurpose for which they are designed, and comparatively inexpensive.

My invention is fully described in the following specification, of whichthe accompanying drawings form 'a part, in which like referencecharacters are used to designate like parts in each of the views, and inwhich Figure 1 is a top plan view of my invention; Fig. 2 is a sideelevation thereof, partly in section on the line 22 of Fig. 1; Fig. 3 isa section taken on the line 33 of Fig. 2, and showing, also, the trayand electrotype shell; and Fig. 4 is a plan view, on a reduced scale,showing one position of the distributer with respect to the trap andelectrotype shell.

Electrotype shells are now usually backedup by being placed in a trayand molten metal poured over the back thereof, directly onto the saidshell, or shells when more than one are arranged in the same tray, butthis causes the molten metal to flow unevenly and sometimes results ininjury to the electrotype shell. By means of my method, however, I pourthe molten metal through my distributor, which consists of a frame 5having a horizontal partition 6 arranged therein at a point intermediatethe height thereof, approximately central as shown, and perforated asshown at 7 to permit the Pa g f the en me al therethr i Specification ofLetters Patent.

but preventing the passage of foreign or deleterio is matter, therebyinsuring the deposit of clean metal on the electrotype shell or shells8.

The frame 5 is provided with handles 9 whereby the device may be placedin position and removed therefrom, and the lower edges of said frame areprovided with a plurality of spaced, segmental, notches 10 therethrough,forming passages of restricted cross-sectional area for the moltenmetal; the molten metal is, therefore, divided into a multiplicity ofstreams of restricted volume, thus insuring an equal distribution of thesame over the electrotype shell and pre venting injury thereto nowoccasioned by the direct impact of the main stream of metal from the pot11.

A further, and highly important, function of my device is to utilize thesame as a weight for maintaining the electrotype shell in contact withthe planetary bottom of the tray 12, and I may use either one or severalof the distributers for each cast or, when only one is used, I may movethe same to different positions for the cast, this use not beingobligatory upon me, however, nor any other method of use, the mainfunction be ing to break up the stream from the meltingpot into aplurality of streams over the entire area of the bottom of mydistributor, and another function being to insure a clean metal for thebacking-up of the shell.

My invention is very simple, though of great value in the art referredto, and, while 'I have described the same as used for backingupelectrotypes, it may also be used for casting stereotypes; further,while I have shown a present preferred form of embodiment of myinvention, it will be understood that I do not desire to limit myself toany specific details, as many changes thereover may be made, within thescope of the following claims, without departing from the spirit of myinvention, or sacrificing its advantages.

Having fully described my what I claim as new, and desire by LettersPatent, is

1. A device of the class described, comprising a frame having ahorizontal partition therein provided with vertical perforationstherethrough, and having a plurality of restricted. passages at thelower edge thereof fo th m ten m a invention, to secure 2.
